eb22a7b210 PyRNA API support for matrix types as Mathutils matrix (with callbacks) rather then a generic rna sequence of floats.
Any 3x3 or 4x4 rna matrix will automatically be returned as a Mathutils matrix.
This makes useful stuff like multiplying a vector location by an object matrix possible.
 ob = bpy.data.scenes[0].objects[0]
 print (ob.data.verts[0].co * ob.matrix)

Also added mathutils matrix types to the BGE GameObject.localOrientation, worldOrientation

* MT_Matrix3x3 added getValue3x3 and setValue3x3, assumed a 4x3 float array.
* KX_GameObject.cpp convenience functions NodeSetGlobalOrientation, NodeGetLocalOrientation, NodeGetLocalScaling, NodeGetLocalPosition.
* 2.5 python api now initializes modules BGL, Mathutils and Geometry
* modules py3 PyModuleDef's use PyModuleDef_HEAD_INIT, rather then {}, was making msvc fail to build.
* added macros for Vector_ReadCallback, Vector_WriteCallback etc. to check if the callback pointer is set before calling the function.

cb89decfdc Merge of first part of changes from the apricot branch, especially
the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:

* GLSL support in the viewport and game engine, enable in the game
  menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
  gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
  storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.

* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
  An extra texture slot shows up once the last slot is used.

* Memory limit for undo, not enabled by default yet because it
  needs the .B.blend to be changed.
* Multiple undo for image painting.

* An offset for dupligroups, so not all objects in a group have to
  be at the origin.

99fdf27af9 Sync with Apricot Game Engine
=============================

* Clean up and optimizations in skinned/deformed mesh code.
* Compatibility fixes and clean up in the rasterizer.
* Changes related to GLSL shadow buffers which should have no
  effect, to keep the code in sync with apricot.

d5f4b3620f Fix for bug #8680: GameLogic.getRandomFloat() returns very small
values on 64 bit, instead of range 0..1. Also a warning fix.

5d0a207ecb Patch from GSR that a) fixes a whole bunch of GPL/BL license
blocks that were previously missed; and b) greatly increase my
ohloh stats!

3444d6612a Delta Loc/Rot/Scale Ipo curve are now supporting in the BGE with the following limitations:
1. All Ipo channels are now independent. 
In Blender 2.45, all 3 Loc Ipo channels were automatically set
together. For example, having just a LocX Ipo channel was sufficient
to fix the X, Y and Z coordinates, with the Y and Z value taken
from the object original Y and Z location in Blender. The same
was true for the 3 Rot and the 3 Scale Ipo channels: the missing
channels were assumed to have constant value taken from the object
original orientation/scale in Blender.
With this patch, all Ipo channels are now independent. 
THIS WILL CREATE BACKWARD COMPATIBILITY PROBLEM if you omit to
define the 3 channels of a same type together in your Blend file:
the undefined Loc, Rot, Scale coordinates of the object will
be influenced by the parent/spawner Loc/Rot/Scale in case the
object is a child or dynamically created.

2. Delta Loc, Rot, Scale are now supported with the following
limitations:
- The delta Loc/Rot Ipo modify the object global (NOT local)
location/orientation
- The delta Scale change the object local scale
- The delta Ipo curves are relative to the object starting
Loc/Rot/Scale when the Ipo was first activated; after that, the
delta Ipo becomes global. This means that the object will return
to this initial Loc/Rot/Scale when you later restart the Ipo
curve, even if you had changed the object Loc/Rot/Scale in the
meantime. Of course this applies only to the specific Loc/Rot/Scale
coordinate that are defined in the Ipo channels as the channels
are now independent.

3. When the objects are converted from Blender to the BGE, the
delta Loc/Rot/Scale that might result from initial non-zero values
in delta Ipo Curves will be ignored. However, as soon as the
delta Ipo curve is activated, the non-zero values will be taken
into account and the object will jump to the same Loc/Rot/Scale
situation as in Blender. Note that delta Ipo curves with initial
non-zero values is bad practice; logically, a delta Ipo curver
should always start from 0.

4. If you define both a global and delta channel of the same
type (LocX and DLocX), the result will be a global channel equivalent
to the sum of the two channels (LocX+DLocX).

ae9dcb3dc2 Update SConscript.
Fix some warnings.
Merge with latest soc code.

What changed in IK lib:

Fully restructured, with components now as follows:
  - IK_Solver: C <=> C++ interface
  - IK_QSegment: base class for bone/segment with 0
    to 3 DOF
  - IK_QTask: base class for a task (currently there's
    a position and a rotation task)
  - IK_QJacobian: the Jacobian matrix, with SVD
    decomposition, damping, etc
  - IK_QJacobianSolver: the iterative solver

The exponential map parametrization is no longer used,
instead we have now:
  - 3DOF and 2DOF XZ segments: directly update matrix
    with Rodrigues' formula
  - Other: Euler angles (no worries about singularities
    here)

Computation of the Jacobian inverse has also changed:
  - The SVD algorithm is now based on LAPACK code,
    instead of NR, to avoid some problems with rounding
    errors.
  - When the problem is underconstrained (as is the case
    most of the time), the SVD is computed for the transpose
    of the Jacobian (faster).
  - A new damping algorithm called the Selectively Damped
    Least Squares is used, result in faster and more
    stable convergence.
  - Stiffness is implemented as if a weighted psuedo-inverse
    was used.

Tree structure support.

Rotation limits:
  - 3DOF and 2DOF XZ segments limits are based on a swing
    (direct axis-angle over XZ) and twist/roll (rotation
    over Y) decomposition. The swing region is an ellipse
    on a sphere.
  - Rotation limits are implemented using an inner clamping
    loop: as long as there is a violation, a violating DOF
    is clamped and removed from the Jacobian, and the solution
    is recomputed.

Convergence checking is based now on the max norm of angle
change, or the maximum number of iterations.

e5304a967c Disabled assert foolery in Decimator. :)
Code provided by Matthew Plough. Verified to run OK in OSX, Windows.

Solves bug #2598, which crashed blender on using non-manifold meshes with
decimator.

55af35d795 I'll break this commit into two sections in the moto files
I got rid of a few warnings about blah shadows a previous declaration.

In the gameengine files I fix the following:
	removed some unused vars
	removed dos style line breaks
	added newlines to last line in a couple of files to remove warnings.

cb289b215f Advanced MT_assert macro.
It will attempt to break into the debugger instead of aborting the program.  On Windows you have a nice MessageBox function, so you can choose to break, ignore, or permanently ignore the assert.

4f2e57a541 Fix bug #2006:
Floating point imprecision made MT_Quaternion::angle return NaN, since acos(x) is NaN for |x| > 1.

Because of the way NaN's propagate through float math, the view pos would be set to [NaN, NaN, NaN] resulting in a grey screen.

f24be4c6ad rewind of previous commit as some experiment bad problems.
This means that bug #1292 is alive again unless you define MT_NDEBUG
which I doubt many do.

e06fba8a1d changed MT_NDEBUG macro to a MT_DEBUG one and reversed defines
So now by default, assert is not used in moto code.

If you want to use assert (and stop blender if one fail),
define MT_DEBUG.

solve bug #1292 and better fix for #1260
